Hy,

I'm newbie on MapPoint 2004 and i'm actually working on a sharepoint portal, so i would develop a webpart to display Business informations on a mapPoint map according to informations entered by users.

My simple question is, it is possible to display a dynamic map (we want users have the possibility, for example, to select a pushpin on the map) in a web page with the mappoint 2004 desktop version (not the web services version).
Is it possible and how ?

I have tried many things with the MapPoint 2004 object model without success . I post my code (in c# in visual studio 2003) and i hope somebody will can help me.

Any response will be appreciated


In my project, i have referenced the MapPoint COM library : Microsoft MapPoint 11.0 Object Library (Europe).

Below, the code of my webform (this code returns an error on the DisplayDataMap Method : incorrect parameter) :

Hi,

Did you also try in a regular Winform ? maybe the webform give the problem?

I use MapPoint 2004 to generate maps as gifs (with save as web page), then I display the gif in the webform.

I catch client script events such as click on map, drag and so on and I command MapPoint 2004 to zoom in that point etc.

MapPoint 2004 runs under a Window Services I created (I don't like using ocx, com objects under IIS) and i communicate from webform and window services by Sockets.

Hi,

But I repeat my question:
- did you try in a regular winform ?
- did you try in a normal application ?
If you dont then we cannot dscover where the problem is.

Hey,

Sorry Wilfried for the delay.

I don't try in a regular winform because i want to display MapPoint maps in a web application (in sharepoint) so i think i can just create webforms not winforms.

I'm not very experimented with web application but i think it's not possible to display a winform in a web application. If it is possible, it's probably the solution but i don't know.

thanx for your interest for my problem.

Hi,

Impossible to find solution withoud first try to find out where the problem is

Ok Wilfried.
I will try to display a map on a winform. I think it will be more easer because i will be able tu use the MapPoint of activeX control.

Michele, could you give some example of javascript of your solution ? With your solution can you know where the user click on the generated map (for example, on a particular city) ?

Thanx

This is not a complete code but I hope it can be useful for your needs.

This is the tag for the image map
<asp:image onmouseup="EndDrag(event);" onmousemove="Dragging(event);" onmousedown="StartDrag(event);"
id="imgMap" ondrag="window.event.returnValue = false;window.event.cancelBubble = true;"
style="Z-INDEX: 128; LEFT: 0px; POSITION: relative; TOP: 0px; dislay: none" onclick="ClickOnMap(event);"
BorderColor="Transparent" Runat="server" src="" alt="" width="686" height="566"></asp:image>

This is the javascript function ClickOnMap()

function ClickOnMap(e){
...
x = document.body.scrollLeft + e.clientX;
y = document.body.scrollTop + e.clientY;

hidXMap and hidYMap are hidden text field
Form1.hidXMap = x;
Form1.hidYMap = y;
//You submit the page, so Form1_PageLoad() server script will be fired
Form1.submit();
//Now I use Ajax technology to avoid entire page refresh instead of Form1.submit(), but for the example I miss it.

}

You must implement zoomout and pan too.

Server side code (c#)

void Page_Load(){

//hidCurrMethod is a hidden text box that stores the current method selected by the user (you can use checkbox like chkZoomIn, chkZoomOut and so on to set the value)
if (hidCurrMethod.value == 'ZoomIn'){

Pan(X,Y);
MapPointObject.ActiveMap.ZoomIn();
MapPoinObject.ActiveMap.SavedWebPages.Add(GifName) ;
//Now I set the image in the browser as the new map
imgMap.src = GifName;



}


}
